Hi guys i wonder how to make the enemy hit you when he saw you and if is out of the range then it will proceed back to his waypoint. I have actually done the search target script as well as the waypoints from the web, but both is in different file when i put them together it cant see to work, any1 know why? I have separate it back to two file.
Waypoint.cs
using UnityEngine;
using System.Collections;
public class SeekSteer : MonoBehaviour
{
public Transform[] waypoints;
public float waypointRadius = 1.5f;
public float damping = 0.1f;
public bool loop = false;
public float speed = 2.0f;
public bool faceHeading = true;
private Vector3 currentHeading,targetHeading;
private int targetwaypoint;
private Transform xform;
private bool useRigidbody;
private Rigidbody rigidmember;
// Use this for initialization
protected void Start ()
{
xform = transform;
currentHeading = xform.forward;
if(waypoints.Length<=0)
{
Debug.Log("No waypoints on "+name);
enabled = false;
}
targetwaypoint = 0;
if(rigidbody!=null)
{
useRigidbody = true;
rigidmember = rigidbody;
}
else
{
useRigidbody = false;
}
}
// calculates a new heading
protected void FixedUpdate ()
{
targetHeading = waypoints[targetwaypoint].position - xform.position;
currentHeading = Vector3.Lerp(currentHeading,targetHeading,damping*Time.deltaTime);
}
// moves us along current heading
protected void Update()
{
if(useRigidbody)
rigidmember.velocity = currentHeading * speed;
else
xform.position +=currentHeading * Time.deltaTime * speed;
if(faceHeading)
xform.LookAt(xform.position+currentHeading);
if(Vector3.Distance(xform.position,waypoints[targetwaypoint].position)<=waypointRadius)
{
targetwaypoint++;
if(targetwaypoint>=waypoints.Length)
{
targetwaypoint = 0;
if(!loop)
enabled = false;
}
}
}
// draws red line from waypoint to waypoint
public void OnDrawGizmos()
{
Gizmos.color = Color.red;
if(waypoints==null)
return;
for(int i=0;i< waypoints.Length;i++)
{
Vector3 pos = waypoints[i].position;
if(i>0)
{
Vector3 prev = waypoints[i-1].position;
Gizmos.DrawLine(prev,pos);
}
}
}
}
enemy.cs
using UnityEngine;
using System.Collections;
public class Enemy2 : MonoBehaviour {
public bullettower1 bulletPrefab = null;
public Transform target;
public int moveSpeed;
public int rotationSpeed;
float range = 10.0f;
float range2 = 15.0f;
float range3 = 4.0f;
float nextFire = 0;
float fireRate = 1.5f;
float stop = 3.0f;
Transform myTransform;
[SerializeField]
public Transform hand;
void Awake(){
myTransform = transform;
}
// Use this for initialization
void Start () {
GameObject go = GameObject.FindGameObjectWithTag("Player");
animation.CrossFade("idle");
target = go.transform;
}
// Update is called once per frame
void Update () {
float distance = Vector3.Distance(myTransform.position, target.position);
if (distance <= range2 && distance >= range){
myTransform.rotation = Quaternion.Slerp(myTransform.rotation,
Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed*Time.deltaTime);
}
else if(distance <= range && distance > stop){
//move towards the player
animation.CrossFade("run");
myTransform.rotation = Quaternion.Slerp(myTransform.rotation, Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed*Time.deltaTime);
myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;
}
else if (distance <=stop) {
myTransform.rotation = Quaternion.Slerp(myTransform.rotation,
Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed*Time.deltaTime);
}
else if (distance >= range) {
animation.CrossFade("idle");
}
if (distance <= range3)
{
animation.CrossFade("Attack");
if (Time.time > nextFire)
{
nextFire = Time.time + fireRate;
GameObject g = (GameObject)Instantiate(bulletPrefab.gameObject, hand.position, Quaternion.identity);
bullettower1 b = g.GetComponent();
b.setDestination(target.transform);
}
}
}
